Application filed July 30, 1909. Serial No. 510,350.

To all whom it may concern:

Be it known that I, FRANK C. Donnmu'r, a citizen ofthe United States of America, residing at Detroit, in thecounty of Wayne and State of Mi higan, have invented certain new and usefu Improvements in Pocket- Atomizers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a pocket atomizer, and more especially to an arrangement thereof .whereby the arts are readily cleansed, and also Where y a comparatively small quantity of medicament is used to produce a large volume of vapor.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings, Figure l,is a View in longitudinal section of a pocket atomizer emodying features of the invention; Fi 2 is a plan view thereof with delivery tu e removed; Fig. 3 is a view in detail, enlarged, of an intake air valve.

Referring to the drawin s, an air chamber 1 and medicament hol er 2, preferably similar cylinders secured together in parallel relation, and, if molded of rubber or like material, integrall formed, are each provided with central y apertured caps 3 and 4 screw-threaded or otherwise detachably secured in their open, upper ends, the bottom of the cylinders bein permanently closed. A leather disk 5 with tongue or flap 6, is seated in a counterbored recess in the base of the air chamber 1, so as to form an inwardly opening valve closure over an opening 7 into a diametrically disposed air inlet duct 8. A piston 9 with return spring 10 in the air chamber, is reciprocable by means of a piston stem 11 extendin through the aperture of the cap 3. The ange 12 of the latter is deeper than the width of the piston and is seated in the counterbored end of the air chamber so that the inner periphery of the flange is flush with the inner periphery of the chamber, and the piston, when at the upper limit of its stroke, is wholly Within the cap. The piston has a soft leather or rubber packing ring 13.

A diametrically disposed duct 14. isdrilled or formed across the base of the holder 2, its outer end being closed by a removably secured cleaning pug 15, and its inner end opening upward y into the lower end of the 1 air cylinder. An atomizing tube 16 isscrewthreaded or otherwise ren'iovably secured in the holder base with its,bore communicating with the duct 14. An outer tube 17 concentric thereon, has a spray orifice 18 in communication with a longitudinal passage '19 ,formed between the tubes fromthe lower end of the outer shorter one to said orifice by flattening or grooving the peripher of the inner tube lon itudinally. A milled head 20 or the like aiiords means for readily unscrewing the tube for clean ing. The cap 4 has a deep flange 21 whose o'wer portion is ada ted to form a close slide fit with the hol er wall, the edge 22thereof being made very thin to yieldingly conform to tumor irregularities and insure against leakage, while the portion near the cap body h asthe screwthreads or other outerlocklng means. A nasal tube 23 or other preferred discharge member is removably secured in the aper ture of the cap 4; 4

By this construction, the passa es and tubes may be all readily opened for c eaning, and there is no packln to get in contact with the contents. Furt ermore, as the piston is within the cap when the latter is unscrewed, and may be readily replaced in the cap when reassembling the atomizer, there is no difliculty in inserting the soft flaring rim of the piston packing in the chamber.

Obviously, changes in the details of construction may be made without departing from the spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts.

\Vhat I claim as my invention is 1. An atomizer. comprising a pair of cylinders secured together in arallel relation and permanently closed at tleir lower ends, one of the cylinders forming a medicament holder and the other an air chamber, a cap detachably secured in the upper end of the holder provided with a depending flan e adapted to yielding y seat itself closely against the inner periphery of the holder, a cap detachably secured in the upper end of the air chamber, an inlet air valve in the base of the chamber controlling an inlet duct extending radially to the cylinder periphery, a piston reciprocable in the chamber, a stem therefrom extending through the cap, a return spring for the piston, an atomizing tube detachably secured in the holder with its lower end in communication with a one of the cylinders forming a medicament cleaning. plug deof the duct. air of cylholder and the other an air chambera cap detachably secured in the upper end of theholder provided with a depending flan e adapted to yieldingly against the inner periphery of. the holder, a cap detachably secured inthe upper end of the air chamber, an inlet air valve in the base of the chamber consisting of a flexible disk seated in-a counterbored recess in the chamber base with duct extending radially from the recess to the cylinder periphery, a piston reciprocable in the chamber, a stem therefrom extending through the cap, a return spring for the iston, an atomizingtube detachably secured in the holder with its lower end in communication with a duct leading transversely through thebase into the chamber, and a cleaning plug detachably secured in the outer end of the duct.
